Author: rmacklem Date: Fri May 9 00:19:08 2014 New Revision: 265721 URL: http://svnweb.freebsd.org/changeset/base/265721 Log: MFC: r264842 Modify the NFSv4 client's Pathconf RPC (actually a Getattr Op.) so that it only does the RPC for names that are answered by the RPC. Doing the RPC for other names is harmless, but unnecessary.
